Specification of Letters Patent.

Patented Nov. 21, 1905.

Application filed March 24, 1905. Serial No. 251,823.

To (all whom it may concern:

W'alla, in the county of Walla Walla and State of \Vashington, haveinvented a new and useful Pump, of which the following-is aspecification.

This invention relates to mechanism of that class employed for thepumping of liquids, and has for its principal object to utilize thepressure exerted by an explosion of gas or a gaseous compound for thepurpose of driving a body of liquid from a pumping-chamber and afterwardutilizing the vacuum created by the condensation of such gases in againfilling the chamber with water preparatory to a second explosion, themechanism being of such character that when once set into operation thepumping will continue so long as fuel is supplied thereto.

A further object of the invention is to provide a pumping mechanism ofthe character described in which the explosive mixture is admitted tothe pumping-chamber and exploded at the proper time, both operationsbeing controlled by a float so arranged that when the proper volume ofwater has entered the chamber the explosion will occur and a delinitequantity of liquid will be expelled from the chamber, a further objectin this connection being to provide means whereby a portion of theexploded gases or products of combustion may be allowed to escape fromthe chamber in order that the remaining gases may be quickly condensedto form a partial vacuum.

A still further object of the invention is to provide improved means forcontrolling the quantity of fuel, either crude or refined oil, admittedto the chamber and to insure the delivery of exactly the same quantityof fuel at each operation.

A still further object of the invention is to provide a simple andeconomical form of vaporizing apparatus in which the fuel in liquid formmay be vaporized and more readily intermingled with the air to producethe explosive compound.

A still further object of the invention is to provide a pumpingmechanism in which provision is made for permitting the escape of excessair from the air chamber or bell, so

that the operation of the pump may be made uniform.

With these and other objects in view, as will more fully hereinafterappear, the invention consists in certain novel features of construction and arrangement of parts, hereinafter fully described, illustratedin the accompanying drawings, and particularly pointed outin theappended claims, it being understood that various changes in the form,proportions, size, and minor details of the structure may be madeWithout departing from the spirit or sacrificing any of the advantagesof the invention.

In the accompanying drawings, Figure l is v a vertical sectional view ofa pumping mechanism constructed in accordance with the invention. Fig. 2is a detail sectional view of the fuel-injector. Fig. 3 is a sectionalelevation drawn to an enlarged scale andon aplane at a right angle tothe mechanism as shown in Fig. 1, illustrating particularly the valvesfor the admission of air and the igniting-flame to the pumping-chamber.Fig. A is a detail perspective view of the valve for controlling theadmission of air to the pumping-chamber. Fig. 5 is a sectional plan viewof said valve. Fig. 6 is aview similar to Fig. 1, illustrating aslightly-modified construction of pump.

Similar numerals of reference are employed to indicate correspondingparts th roughout the several figures of the drawings.

The apparatus forming the subject of the presentinvention is'designed asa cheap and eflicient substitute for the ordinary type of pistonorplunger pumps, and in its simplest form includes means for admittingan explosive compound to a water-containing chamber and for igniting thecompound, so that the force of explosion may force the water from thechamber, the gases on condensing creating a partial vacuum within thechamber and a fresh volume of water being introduced thereinto underatmospheric pressure.

The pumping-chamber 10 is preferably in the form of an upright cylinderand at its lower end communicates with an air-chamber, suitable one-wayvalves 12 being introduced between the chambers to prevent the backflowof the fluid to the chamber 10. Leadinginto the lower portion of thechamber 10 is a suctioninlet-pipe13,havingasuitablecontrollingvalve 14,and one-way valves 15 are employed to prevent the backflow of water fromthe chamber to the pipe. From the lower portion of the air-chamber 11leads an educt-pipe 17 through which the water is forced to any desiredpoint. In the lower portion of the chamber is a dash-pot 18, arrangedfor the reception of a float 19, that fits rather loosely within thedash-pot, and the bottom of the dash-pot has an opening 20, throughwhich the water or other liquid may enter. This float is so arrangedthat it will not be raised by the water until the latter has nearlyreached the level at which the explosion is to occur, and when thislevel is reached the float will move up quickly and will effect insuccessive order the entrance of the charge of fuel, the volume of airnecessary to intermingle with the fluid to form an explosive compound,and the igniting of the mixture, so that the explosion cannot occurprematurely or until the desired volume of water has been admitted tothe chamber.

At one side of the chamber is a vaporizing apparatus, preferably in theform of a pair of concentric cylinders 20 and 21, the cylinder 20opening at the outside of the casing and the cylinder 21 having an openend facing the interior of the casing or pumping chamber. The inner andsmaller cylinder 21 forms a retort into which the charge of liquid fuelisinjected, and said retort is constantly heated by a burner 22 of anyordinary construction, said burner being connected by pipes 23 and 24 toa tank 25, containing gasolene, crude oil, or other liquid fuel.

The inner cylinder is provided with a port 27, that is normally closedby a valve 28, carried by a slidably-mounted stem 29, that is adapted tosuitable brackets within the pumping-chamber, and said valve is normallyheld to its seat by a counterweighted lever 31, pivoted on a suitablesupporting-bracket 32. The lever 31 is provided with an upwardlyextending and curved tappet-arm 33, with which may engage a suitablevalve-operating arm 34.

At a point below the horizontal plane of the retort the casing isprovided with an air-inlet opening 36, that is normally closed by aslidably-mounted valve 37. This valve is wedgeshaped in form, its outerinclined edge being supported by a pair of correspondingly-inclined arms'38, that are spaced from each other to permit the passage of a lug 39,carried by the valve, and when the valve is allowed to move down bygravity its'inclined face bearing against the inclined arms 38 willforce said valve tightly to its seat and effectually close theair-entrance opening 36.

To the top of the float is connected one end of a lever 38, the oppositeend of which is pivoted to a bracket 39, carried by the inner wall ofthe chamber, and pivotally connected to this lever is an arm 40, havinga lug 41 for engagement with the lug 39, so that when the float is movedupward the two lugs will engage and the air-valve will be opened toadmit the quantity of air necessary to mingle with the gas in theformation of an explosive compound. The arm is continued upward and ispivotally connected to the tappet-arm 34, the connection between the twobeing such that the arm 34 may yield in but one direction, and duringupward movement of the arm it will engage with the tappet-arm 34 tomomentarily open the valve 28, and thus explode the gases in the retortby contact with the flame of the vaporizing-burner, after which the armwill pass up beyond the arm 33, and on downward movement of the float.the arm will yield to permit its ready passage below the tappet 33, itbeing understood that the opening of the valve 28 is but momentary, saidvalve instantly closing under the action of the counterweighted lever31.

At a point diametrically opposite the vaporizer 21 is a fuel-injectingnozzle 43, which is in communication with the tank 25 through the mediumof the pipe 24, the flow of oil from the nozzle being normally preventedby a valve'45, adapted to a suitable seat within the nozzle. This valveis carried by a suit ably-guided stem 46, having at one end an enlargedhead 47, and between the guide and head is a helical compression-spring48, that tends normally to hold the valve in its closed position. Theouter portion of the nozzle is extended to form a cylinder 50, having atone end a stuffing-box 51, through which extends a combined plunger andvalve 52. The outer portion of the plunger is threaded and extendsthrough an opening formed in a guiding-bracket 58, and on the threadedportion of the plunger is a nut 59. between which and the stufling-boxis arranged a compression-spring 60, tending normally to maintain theplunger in the position shown in Fig. 2, so that the space between thevalve 45 and the pipe 24 may be filled with liquid fuel from the tank25. By suitably adjusting the nut 59 the front end of the plunger may bemoved in or out for some distance and increase or decrease the quantityof fuel admitted to the pumpingcylinder. To the rear end of the plungeris connected a stem 61, the rear end of which fits within a suitableopening in a guiding-bracket 62, and said stem is threaded for thereception of a pair of adjustable nuts 63, with which engages a lever64, that is moved by the upper end of an operating-lever 64, fulcrumedto a bracket 65, projecting from one side of the chamber. The lower endof the lever 64 is connected by a link 65 to one arm of a bell-cranklever 66, arranged within the lower portion of the pumping-chamber, theopposite arm of said bell-crank lever being connected to a stem 67,depending from the float 19. It is obvious that when the float iselevated the upper portion of the lever 64 will be moved inward, and byengagement with the nut 63 or with an intervening lever 64 the plungerwill be moved forward and will eject from the nozzle a certain quantityof liquid fuel, the quantity depending on the extent of movement of saidplunger, and this may be regulated by proper adjustment of the nut 63.When the plunger moves forward, it will first engage with the head 47 ofthe valvestem and will open the valve to permit the free passage of thefuel, the latter being ejected directly into the retort space 21 andinstantly transformed into vapor and intermingled with the airpreviously admitted by the opening of valve 37.

Near the lower portion of the pumpingchamber is arranged a port 68 forpermitting the exhaust of a portion of the exploded gases or products ofcombustion immediately after each active pumping operation. This port isnormally closed by a valve 69, that is provided with a projecting stem70, and in alinement with but separated from the stem is a stationarylug 71. Projecting from the casing are guides for the reception of avertically-movable rod 72, having a wedge-shape upper end that may beforced between the end of the stem 70 and the lug 71, the parts beingnormally held in this position by a coiled compression-spring 73, sothat the valve cannot be opened under the force of the explosion.

Near the lower end of the float 19 is an annular groove 75, the walls ofwhich are inclined or rounded, and said groove is adapted to receive aslidable rod 76, that normally is pressed into engagement with thegroove by a leaf-spring 77. This rod serves as a retard ing means forholding the float in its lowest position until the water has reached acertain level and overcomes the resistance offered by said rod. The rod76 extends outside the wall of the pumping-chamber and is provided withan inclined arm 78, adapted to engage and exercise a camming effect on aprojecting pin 79, carried by the vertically-movable rod 72. When thefloat moves upward, the rod will ride out of the annular groove, and theinclined arm acting on pin 79 will depress the latter until itswedge-shape end is free from contact with the stem 70 and lug 71,whereupon the valve 69 is free to open; but at this time the valve-willbe held closed by atmospheric pressure, owing to the partial vacuumwithin the pumping-chamber. Immediately after the bottom of the floatpasses beyond the rod the spring 73 will elevate the rod 72 and thevalve will be again locked in place.

In the upper portion of the pumping-chamber is a sparking plug 82, thatis connected in circuit with a battery and sparking coil 83,

l of any ordinary construction, and in the circuit is amanually-operable circuit-closer 84, by which the sparking circuit maybe established once or twice at the beginning of operations; but afterthat the operation of the pump will be entirely automatic.

At the top of the pumping-chamber is an ordinary form of safety-valve85, which may be held to its seat by a counterweight or spring.

In the operation of the parts thus far described the explosive charge isadmitted to the pumping-chamber and is exploded by closing the circuitof the sparking plug. The air within the chamber is driven out throughthe check-valves 12 to the chamber 11, and when the products ofcombustion have condensed a partial vacuum will be formed within thepumping-chamber, so that water or other fluid will enter through thesuction inlet-pipe 13 un der atmospheric pressure, the water flowing upinto the pumping-chamber until the float 19 is almost submerged. Thebuoyancy of the float then overcomes the resistance offered by the rod 61, which acts in the nature of a restoring means, and as the float iselevated the airvalve is opened, admitting a quantity of air, and theplunger 52 is operated to force a charge of gasolene or other liquidfuel into the retort 21. The vapor from the liquid fuel and the aircommingle to form an explosive compound, and this charge is ignited bythe open ing of the valve'28. When the explosion occurs, the water orother fluid within the chamber 10 will be forced past the check-valves12 into the air-chamber 11, and during the outflow of water the float 19will gradually descend, this movement to some extent being retardedbythe dash-pot 18. When thelower end of the float strikes the rod 76,the latter will be moved outward and its cam-like arm 78 will depressthe rod 73, so that the port 68 will be opened under the pressure of theexploded gases and a portion of the products of combustion will escapeto the atmosphere. This operation occurs very quickly and the float incontinuing to move down will again present its groove in alinement withthe rod 76, so that the port will be again closed, leaving within thechamber a comparatively small quantity of exploded gases. These gaseswill quickly condense, and a partial vacuum will be formed within thechamber, so that water will again flow thereinto under atmosphericpressure, and the operation will continue as before.

The air-chamber 11 is provided with a port 89, that is closed by'afloat-valve 90. This port permits the escape of any excess air in thechamber, but is closed as soon as the water elevates the float, andthereafter the volume of air above the level of water is compressed andserves after the explosion of the charge to force the water from thechamber out through the discharge-pipe 17.

In Fig. 6 is illustrated a slight modification, whereinelectromagnetically-controlled operating devices are employed foreffecting the several operations. In this case the construction of thefuel-injector is the same as that previously described with theexception that ICC ITO

j by the counterweight.

the operating-lever 64 is in the form of an armature arranged within thefield of force of an electromagnet 92. This electromagnet is connectedin a circuit including a revoluble circuit-closer 93, mounted insuitable bearings in the upper portion of the casing and having aprojecting lug 9 1 for contact with alug 95, carried by avertically-movable stem 96, the lower end of which is secured to afloat97 within the chamber. The movable contact member 93 is provided with acounterweight 98, that serves to return the same to an initial positionimmediately after each operation. The float rod or stem 96 is furtherprovided with a contact 99, arranged to engage a stationaryspring-contact 100, that is in circuit with an electromagnet 101,arranged near the lower portion of the casing. When the electromagnet101 is energized, it attracts an armature 102, carried by the lower endof a pivotally-mounted valve-operating lever 103, that is provided atone end with a valve 104, controlling an air-entrance port 105 in thecasing. In the upper portion of the chamber is a spark-plug 106 incircuit with a sparking coil 107, and the terminals of the circuit areconnected to a contact 109 and the armaturelever 103, respectively.Contact 109 is normally engaged by-a spring-pressed contact 110 tocomplete the circuit of the electromagnets 101. The contact 110 isarranged in the path of movement of a block of insulating material 112,carried by the armaturelever 103, and when the latter is moved inwardunder the influence of the electromagnet the block will engage contact110 and will move the same from contact 109, and at the same time asmall lug 113, carried by the armature-lever, will engage said contact109 and close the sparking circuit. In the operation of this mechanismthe float will be elevated by the water until lug 95, wiping past thelug 9 1, closes the circuit of the electromagnet 92 and operates theplunger to inject the liquid fuel into the vaporizer. As lug 95 ridespast the lug 94 the revoluble contact 93 will be restored to its initialposition On continuing the upward movement of the float contact 99 willengage contact 100, and thereupon the circuit of the electromagnets 101will be completed and the armature 102 will be attracted, thus openingthe valve 10 1 and allowing a sufficient quantity of air to enter thepumpingchamber to commingle with the vapor and form an explosivecompound. The movement of the armature-lever forces the block 112against spring-contact 110, thus breaking the circuit of theelectromagnet 101 and establishing the sparking circuit, the operationsbeing carried on in successive order and so rapidly that only a smallvolume of air will be admitted to the pumpingchamber.

In order to prevent the valve 104 opening after condensation of gaseswithin the pumping-chamber, a lock 112 is preferably employed, said lockbeing connected to a suitable float 113, which will maintain the valvein closed position until the water has reached a predetermined level.

With an apparatus of this class the ordinary plunger-operated pumpingmechanisms may be dispensed with and large volumes of water may beraised at a minimum expense to any desired height. The mechanism,moreover, is of such character as to require practically no attentionafter the proper adjustment of the parts has been effected.
